ROTARY MOTO R.

SPECIFICATION forming' part of Letters Patent No. 263,510, dated August 29, 1882.

Application tiled March 28, 1882. (No model.)

To all whom it may concern Be it known that I, WILLIAM JOHN GURI), of Sarnia, in the county of Lambton, inthe Province of Ontario, in the Dominion of Ganada, have invented certain new and useful Improvements in Rotary Motors; and I hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to a rotary motor of that class wherein the inflow-pressure acts upon diametrically-reciprocated buckets of the driving-wheel, and the object of the invention is to obtain uniformity ot' motion.

The invention consists ofa cylindrical wheelcase having inlet and outlet apertures in close proximity, an intervening abutment in frictional contact with a driving-wheel concentrically journaled within the case, said wheel having radially-sliding buckets which are receded and projected by cams in front of the abutment, and locked after being projected until again receded by cams on theheads ofthe wheel-case.

Figure l is a plan of the interior of the cylindrical wheel-case, the wheel removed. Fig. 2 is an end view of the wheel removed from the case. Fig. 3 is a section of the wheel on line Z Z, Fig. 2. Fig. 4 is a section ofthe case on line X X, Fig. l. Fig. 5 is a plan of the inner side of the heads of the case with cam. Fig. 6 is an end view of the wheel, the buckets and yokes removed. Fig. 7 is a section of the same on line Y Y, Fig. 6.

A is the cylindrical wheel-case, having inlet B and outlet Cin close proximity, separated by a fixed abutment, D, having an inclined facein frictionalcontactwith thedriving-wheel, which is journaled concentrically in the case by shaft Q, thusrforming an annular waterway between the wall of the case and the face of the wheel of uniform area throughout its entire length, from the induction to the eduction orifices, the abutment diverting the outflow and dividing it from the inow, which passes nearly around the wheel. The face of the wheel and plate E, connecting it to the hub, are radially slotted cruciformly up to the hub, and said slots are occupied by sliding buckets F, which are diametrically connected by yokes Gr G, arranged crosswise, the shaft Q passing through the slots in the yokes.

The drivin g-wheel has dat rims H H, which run in annular grooves I I in the heads of the case, and t therein to run without leakage.

K K are cams afxed at the discharge-outlet in advance of the abutment D, and against which cams the buckets successively impinge and are thereby forced inward, thus permitting the buckets to pass the abutment, and at the same time project diametrically, the opposite bucket t0 receive impulse from theiniow through passage B to drive the wheel. The buckets are connected so that a projected bucket is yoked to a receded one, and when projected are held intermittently locked by cams J J on the heads ofthe case,which cams have contact by the rotation of the wheel with the inner end of the projected bucket, and on approaching cams K K the bucket passes from engagement with cams J J, and is free to be acted upon by cams K to pass the abut-nient after discharging the water.

-L is a flat spring, one end fixed to a plate, M, or to abutment D, and to the opposite free end is attached a plate, N.

O is a sheet of packing or leather underlying plate M, with a ap extending under plate N,vto prevent leakage by covering the joint between the wheel and the abutment, the packing or leather liap being held frictionally against the wheel bythe tension of the spring exerted upon plate N asserted by pressure ot' the inflow.

P is a strip of packing or other flexible material secured to the ends of the buckets to sweep the wall of the case, and thereby prevent leakage while the buckets are locked by the cams J J.

The shaft Q isjournaled in boxes R on the heads of the case A. These boxes R are each formed with an internal cavity, r, and also with an external screw-thread, r. Within the cavities r suitable packin g-rin gs or materials, r", are placed. Upon each box R is screwed a cap, R', formed with an internal screw-thread, r, and a hole, ri", in the top of said cap, through which the shaftQ passes. When the nuts or caps R are screwed upon the boxes 1t, the packings r being in proper position, water-tight bearings are formed for the shaft Q.

When the motor is in operation the inflow passes by the end of a closed bucket at a quarter-section from the inlet before striking a bucket fully projected at the half-section, the

pressure remaining' in said open or projected with a concentric wheel mounted centrally upbucket during' the next quarter-rotation of the wheel, and discharges the Water through the outlet during,` the fourth quarter-rotation, two buckets. momentarily taking the inflow until one is cut ott' by the full projection ofthe other intercepting the inflow.

1 have herein specified the motor as applicable for operation b y Water; but I do notcontine myself to the use ot' any particular pressure, as steam and gaseous tiuids may be used with good results.

I claim as my invention- 1. In a rotary motor, the cylindrical case A, provided with induction and eduction apertures B and C, cam K, and abutment D, said abutment being provided with plates lll and N, packing,` O, and spring,` L, in combination on a shalt within the casing, and provided With buckets F and yokes Gr, substantially as and for the purposes described.

2. In a rotary motor, the cylindrical case A, provided with the induction and cduction apertures B and C, cam K, abutment D, said abutment being provided with plates M and N, packing' 0, and spring L, and the cam J, in combination with a concentric wheel mounted centrally upon a shaft within the casing, and provided with buckets F and yokes G, Substantially as and for the. purposes set forth.
